taken in connection with the accompanying drawings, forming part of the same.

This invention relates to stills which are particularly ada ted for distilling the heavy mineral oils an in which the oil is passed through the still in an elongated conduit.

In the accompan ing drawings in which the same reference cfiaracter refers to similar parts in the several figures, Figure 1 is a .perspective view of a form of still embodying t is invention, parts being broken away to show the interior construction. Fig. 2 is a partial longitudinal section showing the current producer operating in the conduit. Fig. 3 is a plan view of the same.

The setting A upon which the still chamber is mounted is provided with a furnace of usual construction for heating the several compartments of the still chamber B. This furnace is provided with the ordinary firing doors A A although other firing openings may be provided and if desired the still may be heated by any other well known means. The still chamber is formed as indicated of asubstantiall semi-cylindricalconstruction, the division p ate C separating the still chamber into two compartments B B The man holes B are provided to permit access to the compartments of the still. The vapor from these compartments passes into the vapor drums. D and D and then passes out by the vapor pipes D. A series of partitions G are'formed on the floor of the still chamber, these partitions extending nearly across the Width of the still but allowing in every case a passage G, around the end of the artitions, the other ends of the partitions G eing formed in a similar manner, so that a sta ered conduit for the oil is formed, by

, 9 WhlC 1 the ,OlhlS'COIldUCted in a zigzag 1!liL1lner around the partitions from one endv of I each compartment to the other- A suitable ate C is formed in the division plate '0 hev Iow the normal level of the material in. the still so as to allow this material to pass from the compartment B to the compartment B It will be noted that the partitions in the compartment B are formed in a similar manner to those in the compartment B but that they are spaced more closely so that the height of material in the conduit at this point is sub stantially the same as in the. compartment 13,. In this way by s acin the artitions more closely together t e oi or ot er material is maintained constantly at substantially the same height in spite of the evaporation of the oil. In some cases, it may be desirable to s ace the'partitions so as to vary the widt of the conduit in each of the com' artments of the still instead of spacing al the partitions in the same compartment at the same distance apart. Instead of forming the still chamber with two compartments it may be formed with any desired number of compartments by using the proper'nurnber of division plates.

' The oil or other material is supplied to the. compartment B, by the su ply pipe E and the material flows through the stag cred conduit in this compartment as has een indicated under the influence of gravity, if desired, sincethe still maybe set at a considerableangle, the floor of the still slanting downward from the supply pipe E to the dischar e pipe E where the liquid niaterial is withdrawn from the compartment 13,. In order to accelerate the movement of the material through the staggered conduit a current producer or feeder is provided. This device may take the form indicated in the drawings where a reciprocating current producer F is shown as mounted to move transversely of the still. The current producer is accurately guided during its reciprocation by the wheels gaging the operating ins F when the paddles are acting upon t e material in the conduit and when the paddles move into the in.- active or feathering osition-the heads bear a ainst the sto pins This actionisclearly illustrated in igs. 2 and 3. In Fig. 3 as the current producer moves forward, as indicated 'duit in which these paddles lie.

by the arrow, the paddle heads of the alternate paddles are brought into contact with the o crating pins F and the corresponding padd es then extend transversely across the conduit in operative position and produce a flow of the material in the sections of the con- It will, of course, be understood that the paddles may be formed to engage the sides of the conduit as closely as desired in order to produce the desired flow of material therethrough. During this movement of the current producer, the other paddles move backward into inactive or feathering position, the heads engaging the stop pins F so that these paddles do not have any substantial action upon the material in conduit at this time. When the current producer moves in the opposite direction the action of these two sets of paddles is reversed so that the current producer affects the movement of the material in all of the cotions of the conduit.- The current producer is reciprocated by the oscillating shaft F, which is rotatively mounted in the upper por tion of the still chamber. The arms- F, are rigidly connected to this shaft and the lower to escoping sections F move within these arms and are pivotally connected with the current producer. In this way, as the shaft oscillates the current producer is reciprocated transversely of the still. Any other desired means may be usedfor operating the current producer and any other forms of current producer may be employed for moving the oil or other material along the conduit at the desired rate.

In order to thoroughlymix the oil or other material as it passes along the conduit, suitable weirs G are provided at various points along the conduit, these weirs being formed with the weir notches G through which the oil passes. This is to mix the oil and prevent the stratification of the same. These weirs also prevent to some extent the backward movement of the oil in the conduit. The gates Gr formed in the partitions as indicated in Fig; 1 also have the same function in preventing Stratification. These gates are formed with the opening G, as indicated. The gate C, in the division plate C has the same structure and operation.

In operating this still to carry out the continuous recess of distillation, it is desirable to pass the oil successively through a number of these stills. The various compartments being maintained at difierent temperatures so that the products which vaporize at the difierent temperatures are removed successively, the. lighter portions being removed first and then the heavier portions of the material until finally the residue is removed from the last compartment in a liquid c'ondition. Under some conditions, however, a single still chamber ma be employed and thischambermay be divided into the desired number-of compartments so that the difierent products may be removed successively from the material in a similar manner. a

It is, of course, understood that many modifications may be made in the form of still described without departing from the spirit of thisinvention. Furthermore parts of this invention may be used without employing all of the same. I do not, therefore, wish to be limited to the disclosure which I have made in this case, but
